Echinocystis Lobata
''Echinocystis'' is a monotypic genus in the gourd family, Cucurbitaceae. The sole species is ''E. lobata'', commonly called wild cucumber, prickly cucumber or bur cucumber. It is an annual, sprawling plant that is native to North America. Description ''Echinocystis lobata'' is an annual vine that produces stems that can be as long as and which climb, with the help of coiling, branched tendrils, over shrubs and fences or trail across the ground. The stems are angular and furrowed. The leaves are alternate with long petioles, five palmate lobes and no stipules. The plants are monoecious, with separate male and female blooms on the same plant. The male flowers are in long-stemmed, upright panicles. Each flower has a white, or greenish-yellow, corolla with six slender lobes. The male flower has a single central stamen with a yellow anther. The female flower has a single stigma and is borne on a short stalk at the base of the flower panicle, with the spiky globular inferior ovary b ...

Torr
The torr (symbol: Torr) is a unit of pressure based on an absolute scale, defined as exactly of a standard atmosphere (). Thus one torr is exactly (≈ ). Historically, one torr was intended to be the same as one "millimeter of mercury", but subsequent redefinitions of the two units made them slightly different (by less than ). The torr is not part of the International System of Units (SI). It is often combined with the metric prefix milli to name one millitorr (mTorr) or 0.001 Torr. The unit was named after Evangelista Torricelli, an Italian physicist and mathematician who discovered the principle of the barometer in 1644. Nomenclature and common errors The unit name ''torr'' is written in lower case, while its symbol ("Torr") is always written with upper-case initial; including in combinations with prefixes and other unit symbols, as in "mTorr" (millitorr) or "Torr⋅L/s" (torr-litres per second). The symbol (uppercase) should be used with prefix symbols (thus, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cucurbita Foetidissima
''Cucurbita foetidissima'' is a tuberous xerophytic plant found in the central and southwestern United States and northern Mexico. It has numerous common names, including: buffalo gourd, calabazilla, chilicote, coyote gourd, fetid gourd, fetid wild pumpkin, Missouri gourd, prairie gourd, stinking gourd, wild gourd, and wild pumpkin. The type specimen was collected from Mexico by Alexander von Humboldt and Aimé Bonpland sometime before 1817. In Latin, foetidissima means ill smelling. The buffalo gourd has evolved in the semiarid regions and is well-adapted to desert environments. It contains high amounts of protein and carbohydrates and yields abundant oil. The carbohydrates that are formed in the tap root have led to the idea of growing the plant for biofuel. The fruit is consumed by both humans and animals. When mature, a stage marked by increasing desiccation of vine, leaves, fruit-stem, and fruit, the fruit begins its final gourd stage. Geographic location and genetics make ...

Frass
Frass refers loosely to the more or less solid excreta of insects, and to certain other related matter. Definition and etymology ''Frass'' is an informal term and accordingly it is variously used and variously defined. It is derived from the German word ''Fraß'', which means the food takeup of an animal.M. Clark and O. Thyen. The Oxford-Duden German Dictionary. Publisher: Oxford University Press 1999. The English usage applies to excreted residues of anything that insects had eaten, and similarly, to other chewed or mined refuse that insects leave behind. It does not generally refer to fluids such as honeydew, but the point does not generally arise, and is largely ignored in this article. Such usage in English originated in the mid-nineteenth century at the latest. Modern technical English sources differ on the precise definition, though there is little actual direct contradiction on the practical realities. One glossary from the early twentieth century speaks of "...excrem ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Striped Cucumber Beetle
''Acalymma vittatum'', the striped cucumber beetle, is a beetle of the family Chrysomelidae and a serious pest of cucurbit crops in both larval and adult stages. It is distributed from eastern North America to the Rocky Mountains. It is replaced in the west by '' Acalymma trivittatum'', a duller species often with greyish or pale white elytra rather than yellow. Description The striped cucumber beetle is a small beetle approximately half a centimeter (1/5 inch) in length, and characterized by brown-yellow elytra completely covering the abdomen and longitudinally transversed by three thick black stripes. It superficially resembles the western corn rootworm (''Diabrotica virgifera''), another serious crop pest. However, the ventral abdominal surface of ''A. vittatum'' is black where that of ''D. virgifera'' are yellow, and the elytra of ''D. virgifera'' often do not extend the full length of the abdomen. Life cycle Large numbers of adults emerge from diapause in the spring to fe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Erwinia Tracheiphila
Bacterial wilt is a complex of diseases that occur in plants such as Cucurbitaceae and Solanaceae (tomato, common bean, etc.) and are caused by the pathogens ''Erwinia tracheiphila'', a gram-negative bacterium, or '' Curtobacterium flaccumfaciens pv. flaccumfaciens'', a gram-positive bacterium. Cucumber and muskmelon plants are most susceptible, but squash, pumpkins, and gourds may also become infected. Bacterial wilts of tomato, ''Capsicum'' (pepper), '' Solanum ovigerum'' (eggplant), and Irish potato can be caused by (Burkholderiaceae) ''Ralstonia solanacearum''. Other bacteria in the family Burkholderiaceae can cause bacterial wilt of carnation. Bacteria in the genus ''Xanthomonas'' can cause banana bacterial wilt or bacterial wilt in the genus ''Agrostis''. Disease transmission ''Erwinia tracheiphila'' is spread between plants by two species of insect vectors, striped cucumber beetles (''Acalymma vittatum'') and spotted cucumber beetles (''Diabrotica undecimpunctata'').

Chauliognathus Pensylvanicus
The goldenrod soldier beetle or Pennsylvania leatherwing (''Chauliognathus pensylvanicus'') is a species of soldier beetle (Cantharidae). Nomenclature The specific epithet ' is Latin for "of Pennsylvania". The spelling with one ''n'' was in common use at the time (de Geer says in the description that the specimen was sent to him from 'Pensylvanie'), so the species name based on it cannot be corrected under the rules governing scientific names. Distribution The species is native to North America, and is one of the most common species of soldier beetle in the Midwest. Ecology ''C. pensylvanicus'' has been identified as an important pollinator of the prairie onion. Parasites Adult ''C. pensylvanicus'' may be infected by the fungus ''Eryniopsis lampyridarum ''Eryniopsis lampyridarum'' is an entomopathogenic fungus and its host is the soldier beetle, either '' Chauliognathus marginatus'' or ''Chauliognathus pensylvanicus The goldenrod soldier beetle or Pennsylvania leatherwing ...

Tiphiidae
The Tiphiidae (also known as the tiphiid wasps) are a family of large, solitary wasps whose larvae are parasitoids of various beetle larvae, especially those in the superfamily Scarabaeoidea. Until recently, this family contained several additional subfamilies, but multiple studies have independently confirmed that these comprise a separate lineage, and are now classified in the family Thynnidae. The females of some Brachycistidinae are wingless, and hunt ground-dwelling (fossorial) beetle larvae. The prey is paralysed with the female's sting, and an egg is lain on it so the wasp larva has a ready supply of food. As some of the ground-dwelling scarab species attacked by tiphiids are pests, some of these wasps are considered beneficial as biological control agents. Taxonomy Tiphiid genera are classified as follows: Subfamily Brachycistidinae *'' Acanthetropis'' Wasbauer, 1958 *'' Brachycistellus'' Baker, 1907 *'' Brachycistina'' Malloch, 1926 *'' Brachycistis'' Fox, 1893 ...

Scoliidae
The Scoliidae, the scoliid wasps, are a family of about 560 species found worldwide. They tend to be black, often marked with yellow or orange, and their wing tips are distinctively corrugated. Males are more slender and elongated than females, with significantly longer antennae, but the sexual dimorphism is not as apparent as in the Tiphiidae. Biology Scoliid wasps are solitary parasitoids of scarab beetle larvae. Female scoliids burrow into the ground in search of these larvae and then use their sting to paralyze them. They will sometimes excavate a chamber and move the paralyzed beetle larva into it before depositing an egg. Scoliid wasps act as important biocontrol agents, as many of the beetles they parasitize are pests, including the Japanese beetle. Male scoliids patrol territories, ready to mate with females emerging from the ground. Adult wasps may be minor pollinators of some plants and can be found on many wildflowers in the late summer. Scoliidae also has at least o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
